Another Powermaster question

[BlueLimited87]

If Powermaster is constantly running wether intermittently or continuously what does this sound like? Is it very noticeable in the car & underhood. At idle(foot off brake) I hear a slight clicking noise. Accumulator is good, no light, fluid level good, and breaks work fine.

Powermaster has an electric motor. It does not click....it runs like any electric motor would. You can hear it inside the car, you can hear it outside the car. If you are still unsure, open the hood and listen. And if yet still unsure, put your finger on it. You will feel if it is running.

Read this article, as you will read the PowerMaster Motor should not run more than 15 sec.

The clicking sound could be from a faulty brake switch. It doesn't know if it wants to run or stop.

Wanna bet?? turn up your volume and listen to what mine sounded like when the pressure switch failed yesterday.
